Outgroup

Fig. 2.1. Neighbor-joining tree from Jacobs et al . (2008) showing the clustering pattern of 4929 potato
genotypes using AFLPs. A number of species groups can be distinguished: the North and Central
American diploids, the North and Central American polyploids, Solanum verrucosum (the only
representative of the Tuberosa group occurring in Central America), the South American representatives
of the Tuberosa group, divided in a southern and northern group with the cultivated potatoes joining the
northern group, and the polyploid Acaulia group with representatives in both Central ( Solanum
demissum ) and South America ( Solanum acaule , Solanum albicans ).
